Here I used the occasion to convince the two ladies present that I should be privileged to show to my two buddies Röntgen's lab since I had written way back in 1960 my diploma thesis about: Applying the contrast transfer function to x-ray picturing. Oh miracle, one of the girls left and came back with the key. The room we visited was filled with Ruhmkorff induction coils and Crookes tubes or Hittorf vacuum glass vessels. The picture below may give you an impression.

By the way, applying the contrast transfer function to the picture taken by Röntgen of a hand would have improved the quality of the photo considerably. Please compare the left hand on the left to the left hand on the right.
